The ongoing student demonstrations in Chile began as a protest over the costs, profits, and fairness of higher education there. They have since attracted other segments of Chilean society venting frustration over wages, health care, and other issues. Uniting the protesters is common dissatisfaction with hugely unpopular President Sebastian Pinera and social inequality. Workers joined a 48-hour general strike in August which, like many demonstrations during the course of the protests, was met with police using tear gas and water cannons on the participants. With changes in the education system still unsettled, the student protests are likely to continue. Chileans yesterday celebrated their national independence day. -- Lane Turner (34 photos total)
